    Should I enable UEFI Boot in BIOS before Win 10 install?

    I built a computer back in 2009 with an Intel DP55KG motherboard running Windows 7. So, I am getting ready for a fresh Windows 10 install and I noticed that back in 2009 I never enabled the UEFI boot mode. Would it be recommended to enable it this time before the Win 10 install, or will it bring about some issues? I also have 3 other hard drives in this computer with various flavors of Linux.

    Here is the definition of the setting according to the motherboard manual:

    UEFI boot

    OPTIONS: Enable Disable

    Enables or disables Unified Extended Firmware Interface (UEFI) Boot. UEFI Boot must be enabled in order to boot to a drive larger than 2 TB (terabytes). Enable: BIOS will attempt to boot via UEFI before using the legacy boot sequence. Disable: BIOS will use the legacy boot sequence.

    Windows 3.1 to Windows 10

    UEFI mode is pretty much the standard used by PC's today..
    supports larger disk drives and up to 128 partitions per drive..

    UEFI is not going to work for me. I enabled it to test it out and I lose access to the BIOS menu, which I use to load the Linux installs on the other drives.

    At least the clean install went smoothly. Considerable speed boost, especially with 7 years of accumulated Win 7 garbage buildup being eliminated. I had tried an upgrade from Win 7 a couple of weeks ago and it went miserably; every time I booted, a different blue screen error would pop up.
